Feedback Request: GRT-Supplied VDO Oil & Fuel Pressure Sensors
I'm currently considering removing our existing engine monitor, an AF2500, and replacing it with a GRT EIS system which will more easily interface with the rest of the GRT gear in the panel.
Over the years I've read several threads here indicating the VDO pressure sensors favored by GRT are less-than-reliable.
1) Is this still the case?
2) What other pressure sensors have been used to good effect?
3) If using other pressure sensors, is the GRT EIS capable of calibration to provide accurate indications?
4) Has anybody re-used in their GRT EIS installation the very sleek 3-wire pressure sensors provided as original equipment with the AF2500?
5) If yes to 4, how did you implement them? (Suspect using 4.8V instrument power to energize the sensor, as well as the existing Common connection, with the "middle" signal wire going straight into the EIS pin should work, but don't want to incur additional down-time of the aircraft should this not work.)
Thanks in advance for your well-considered replies.
